Question: If ΔG is negative, what does it indicate about the reaction?

Options:

Correct Answer: Reaction is spontaneous

Solution:

A negative ΔG indicates that the reaction is spontaneous.

If ΔG is negative, what does it indicate about the reaction?

If ΔG is negative, what does it indicate about the reaction?

Step 1: Understand what ΔG means. ΔG is the change in free energy of a reaction.
Step 2: Know that free energy helps us understand if a reaction can happen on its own.
Step 3: Recognize that a negative ΔG value means the energy of the products is lower than the energy of the reactants.
Step 4: Realize that when ΔG is negative, it means the reaction can occur without needing extra energy.
Step 5: Conclude that a negative ΔG indicates the reaction is spontaneous, meaning it will happen naturally.

Gibbs Free Energy – ΔG (Gibbs Free Energy change) indicates the spontaneity of a reaction; a negative value suggests that the reaction can occur without external energy input.
Spontaneity of Reactions – A spontaneous reaction is one that can proceed in the forward direction under standard conditions.
